I don't #foil or know much about the current tech/brand/market/etc but saw this posted on kiteforum and thought I'd post it here. Carafino has some type of 2-for-1 deals for complete foil/board packages. $1500 USD for two, $750 each if you split with a friend.

I can't vouch for the validity of this, or whether this is some scam to get some upfront $$$ for manufacturing costs, or how well this generation of his foils perform... but if you were looking at getting a foil it might be worth looking into.
